Early cervical cancer has no symptoms

Cervical cancer is the second most common cancer in women aged 15-44 years, affecting the cervix- the lower part of the uterus that connects it with the vagina. Most cases of cervical cancer are caused by sexually acquired infection of some strains of the Human Papilloma Virus (HPV)

Cervical screening: The tests and guidelines

Cervical screening is the best way to detect cervical cancer at an early stage, and increases the rate of successful treatment.
Cervical cancer screening requires a doctor or a nurse who takes the exfoliated cells from the surface of the cervix and a pathologist who detects early changes of cancer, if present. Liquid based cytology (LBC) and PAP tests are the two main methods of cervical screening. Both these tests are non-invasive and essentially painless. These tests are important for disease prevention, as they help in detecting any abnormal cell growth in the cervix before it turns cancerous. Screening is recommended for women between 21 and 65 years as majority of women diagnosed with cervical cancer are under 50 years of age; very few are over 65 years of age.

Screening

"When it comes to screening, a doctor who says 'Let's err on the side of caution,' may actually err on the side of reckless ignorance and grave harm."
